IMPROVEMENT IN HYDRANT'COVERS.

Specification forming part of Letters Patent No. 154,4QS, dated August25, 1874; application led 'July 25, 1874.

To all whom it may concerti:

Beit known that I, JAMES MGKNIGHT, of Brooklyn, in the county of Kingsand State of New York, have invented a new and Improved Hydrant-Cover,of which the following is a specification:

The object of my invention is to provide a simple and cheap meansofastening hydrantcovers, whereby they may be more readily connected anddisconnected than they cau be as at present arranged, and at the sametime which is fitted in a centralbearing projecting from the under sideof the cover, and having a socket, G, in the upper end, in which theupper end of the spindle terminates, so that' it can only be turned by awrench, H, which will fit in the socket. The cam will be held inposition for keeping the catches in the notches by friction; but afastening device may be employed for the purpose, if required. Lugs maybe used on the walls of thel hydrant for the catches, instead of thenotches, if preferred.

Having thus described my invention, I claim as new and desire to secureby Letters Patenty The combination of the spring-catches A, cam D, and aspindle, F, with the hydrant U and its ooverB, the hydrant having thenotches E for the catches, and the spindle being arranged in a soeketedbearing to be turned by a wrench, H, all substantially as specified.
